Surface Coatings and Paints
The chapter presents an overview on surface coatings and paints of polyurethane (PU) and its nanocomposites, with special emphasis on biobased hyperbranched PU as a binder. It covers the basic concepts, importance, types, and a brief description of the methods of preparation and characterization of coatings and paints. Special emphasis is placed on the components used, properties, and applications of such coatings and paints. The significance of such biobased paints and coatings within the current scenario of environmental issues is highlighted. The typical problems of industrial paints are also discussed here. Conclusions and future trends on the field of paints and coatings are discussed at the end of the chapter.
